l'lO WHOM IT MAY CONCERN:

Be it known that I, SIGMUND ULLMAN, of the city, county, and State otNew York, have invented a new and improved Envelope; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference beinghad to the accompanying drawings, forming a part ofthis specification.

This invention relates to a new and improved mode of cutting envelopes,whereby the same, when folded and fastened or sealed, will` not admit ofletters or documents being abstracted without defacing or tearing theenvelopes. v

The invention further relates to a new and improved application of aneyelet-seal or fastening to the euvel ope, whereby the former arepermanently attached to the latter, so that they may be sold with them,and purchasers or users enabled to seal the envelopes with the greatestfacility. i i I Hitherto, envelopes which have been sealed with eyeletshave been sold separately from the latter, and th purchasers or userswere required to purchase two different articles, envelopes and eyelets,which causes considerable diH-lculty and embarrassment, and thereforethey have not come intogeneral use.

In the accompanying sheet of drawingsiFigure l represents a view of anenvelope in an open or unfolded state, and cut according to myinveutiou.

Figure 2, an enlarged view of the samein a folded state.

Figure 3, a transverse'section of iig. 2, taken in the line z x, fig. 2.

Figure 4, a view of a portion of the same, in which the seal-eyelet isfitted.

Figure 5, a section of g. 4, taken in the line y y.

Similar letters of reference indicate corresponding parts.

The main portion or body of the envelope is of rectangular form, or hasparallel edges, a a, and ends, b li, and is folded three times, asindicated by the figures 1, 2, 3, in fig. 1.

The portion of the envelope included between the folds 2 and 3 has smalliiaps, c c', at its ends, and these iaps comprise the only variation theenvelope has from a rectangular form. The position of the folds, whenthe envelope is closed up, is vshown clearly in iig. 3, the letter ordocument being shown in red.

`When the fiaps c 4c are turned over, and one eyelet, d, passed throughthem, every part formed by therthree folds, l, 2, and 3, will have theeyelets passing through them, as indicated by the holes ff in iig. 1.

In putting up the envelopes for sale, the eyelet of the Hap c isriveted, and said flap gummed down. The other a p, e', is left open, and'its eyelet, d, secured in it, by gumming a strip of paper or othersuitable material, e, over said eyelet, at the'outer side of the flap,and over the inner side also, if desired,=('see more particularly iig.5.) By this means the eyelet is secured to envelope, and is put up andsold with them, eyelet-holes,'

f', being made through the end of the envelope, to receive the eyelet,sothat all the purchaser or user is required to do, in order to seal theenvelope, is to moisten the inner side of flap c,-turn itover, and passthe eyelet through the holesf, press the ilap against the body of theenvelope, so that it will be gummed thereto, and then rivet the eyelet,which may be done by means of a small punch or other suitable device.

The object in gumming the iiaps c e/ is simply to prevent envelopescatching into cach other in their transit through the mail. The-gummingadds nothing to security; the eyelets are sufficient for that purpose.

The object in folding theenvelope thrce times in the' lines 1, 2, 3, isto produce an increased number of folds for the eyelet to pass through,as each additional foldv increases the diiiieulty of opening theenvelope without detection.

Having described my invention,.l claim as new, and desire to secure hyLetters Patent- Securing the eyelet cZ in the open iap e of the end, hygumming a strip of paper over said eyelet, at the outer side of theflap, as herein shown and described.

SIGMUND ULLMAN.
